Actually the problem is with improper setting of the Active in all the modules which subclass DBD::File (CSV,AnyData, etc). I've fixed it in releases that are almost ready. I also have created a Class::DBI::AnyData/CSV/DBM and Class::DBI::Loader::AnyData/CSV/DBM modules almost ready. If you can't wait until I've tested and released, let me know and I'll send you development versions to play with.
